teen-MIXING MACHINE.

i To all whom it may concern:

This invention relates to mixing machines and has for its object the provision of a machine for mixing preferably hot molasses with alfalfa meal or other ground food stuff whereby to form a feed for cattle.

An important object is the provision of a device of this character which is peculiarly constructed and whereby the different ingredients of the feedv will be thoroughly mixed, the construction being furthermore such as to retard the passage of the material through the device in order to insure thorough mixing.

Another object is the provision of a device of this character including a rotary shaft operating within a casing and carrying a series of mixing blades spirally arranged and disposed gradually closer together toward the discharge end so as to cause the exertion of pressure at the discharge end which will effect the retardation of the discharge.

Another object is the provision of a device of this character which has its discharge end slightly constricted for the same purpose, to effect retardation, and which has a sliding plate associated with the discharge end whereby the outlet opening may be still further decreased in size when desired.

An additional object is the provision of a device of this character which will be comparatively simple and inexpensive in manufacture,' highly eflicient in use, durable in service, and a general improvement in the y art.

Specification of Letters Patent. Patentgqjl J 111mg 13 15922, Application filed March 28, 1921. Serial No. 456,433.

Figure 3 is a vertical longitudinal secis a horizontal longitudinal secthrough,

Figure 7 is a vertical longitudinal sectional view therethrough, and i Figure 8 is a similar view through a further modified form.

Referring more particularly to the draw ings, the numeral 10 designates a horizontally disposed casing of suitable length and circular in cross section, and 11 designates a horizontally disposed casing located below the casing 10 and of greater length whereby to extend beyond one end thereof. The casing 10 is formed in one side with a remov able cover 12 having a handle 13 whereby access may be had thereto. One end of the casing '10 is closed by a head 14 and near this end thecasing is provided with a hop per 15 into which the alfalfa meal or other ground feed is introduced. Adjacent the hopper 15 I'provide an inlet pipe 16 for conducting hot molasses into the casing. The other end of the casing 10 has secured thereon a head 17 which has a central opening 18 of somewhat less diameter than the diameter of the casing 10 and this head 17 is provided with spaced guides 19, between which is slidable a plate 20 having a handle 21 and which is adapted to close the open ing 18 to agreater or less extent, as desired. This end is of course the discharge end of. the casing.

The casing 11 is of oval shape in cross section and the end thereof which extends beond the casing 10 is provided with a hopper 22 adapted to receive material discharged from the casing 10. This end of the casing 11 is closed by a head 23 and the other end has secured thereon a head 24 having a central opening 25, of less diameter than the bore of the casing. Secured upon the head I 24 are guides 26 between which is slidable a blade 27 having a handle 28 and which is for the purpose of regulating the discharge from the casing 11. The casing 11 has one or both sides formed as removable plates Figure 6 is a cross sectional view there-' charge end of the casing 11 is a trough 31 within which is located a screw conveyor 32 whereby the material discharged from the casing 11 may be conducted to any desired location.

Journaled centrally within'the casing is a shaft 33 upon which is mounted a plurality of blades 3% and 35. The blades 3%- are comparatively close together and are arranged at equal distances apart at the inlet end of the casing. These blades are formed double whereas the blades 35 are single and are arranged spirally around the shaft. Any suitable means may be provided for rotating the shaft 33. Journaled within the casing 11 isa pair of shafts 36 which carry blades 37 and 38 arranged in identically the same manner as the blades 34 and 35 and of the same construction. The shafts 36 carryinblades 34 immediately beneath the hopper casing which will prevent too free discharge,

,'and insure thorough co-Iningling'of the inwill agitate and churn together the feed and molasses. As these blades are not spirally arranged they will exert a thorough mixing action upon the material and as they are inclined they will cause the material to be advanced slowly along the casing 10. After leaving the blades 34 the material is engaged by the blades 35 and mixed further thereby. As these blades 35 are spirally arranged upon the shaft 33 they will advance the ma terial toward the discharge end of the casing but as the opening 18 at this discharge end is of less diameter than the internal diameter of the casing 10 there will ensue a retardation of the discharge throughthe opening 18 which will result in a back pressure in the gredients. When necessary, the slidingplate 20 may be moved to constrict thisopening still further so as to increase the retarding action. Material discharged from the casing 10 vwil1. drop into the hopper 22 and pass into the casing 11 in which the operation is continued in thesame mannenethe material being carried along in the casing 11 and being discharged therefrom into the conveyor trough 31. The mixing within the casing 11 should be very thorough as the two sets of blades are provided on the separate shafts working in opposite directions.

While 1 have shown and described the casing 11 as being oval in cross section and provided with two shafts carrying paddles or blades, it will be readily apparent that the section 11 might be of the same construction as the casing 10, that is circular in form and provided with a single shaft, as shown I in Figure 8.

.Referring more particularly to the form shown in Figures 5, 6 and 7, 1 provide a single casing 40 which is provided at one end with'a hopper 451 and a molasses inlet pipe 12 and which has this end otherwise closed and which has its other end provided with a head13 formedwith'an opening 44-. at the sides-of which are disposcd'guides L5 between which is'slidable a plate 46 having a handle 47. This casing is somewhat oval in cross section and elongated, in a-horizontal plane. The casing has portions 18 removable and provided with handles 49. Journaled longitudinally within the casing 10 are shafts 50 disposed one beside the other and these shafts carry intermeshing gears 51 whereby they may be rotated simultaneously in opposite directions when their shaft is rotated by any suitable means, not shown. Secured upon the shaft 50 are paddles or blades 52 and 53, identical in construction and arrangement to the previously described blades 3% and 1n the operation of this form the molasses and feed introduced at the inlet end of the casing will be thoroughly mixed and passed. along the casing by the paddles 53 to the discharge end thereof, the discharge being retarded so that the material will back up and be under pressure so that all parts of the dry material will be moistened with the molasses. The mixed matter of course dis-. charges through the opening 44 in the head 43.

While it is not illustrated, it is readily conceivable that use might bemade of a single cylindrical casing such as the

casing

10 or 11 with the single shaft carrying the blades or paddles. 7

From the foregoing description and a study of the drawings it will'be apparent that I have thus provided a simply-constructed and easily operated device for mixing dry feed with molasses or the like so as to produce a feed designed for use by cattle or other animals. lit will be readily apparent that the construction is such that the mixing action will be thorough and that the device will inevery way efiiciently perform all the functions for which it is inhasa? provided at one end with an inlet hop er and an inlet pipe, said end of the casing eing closed, a head secured upon the other end of the casing and provided with an opening,

a plate slidably associated with said head whereby to partially cover said opening, a shaft rotatable within said casing, and a plurality of mixing blades carried by said shaft.

In testimony whereof I afiix my signature.
